This type of electron tube is called a compound tube. Compound tubes are mainly used in high-power switching circuits, motor speed regulation, inverter circuits and driving small relays.

[0003] Chinese patent CN220523480U discloses a continuous fiber reinforced bio-based polyamide composite pipe. The composite pipe of the utility model includes an inner lining layer, a reinforcement layer and an outer protective layer from the inside to the outside. The composite pipe of the utility model is made by winding the composite pipe reinforcement layer on the outer side of the composite pipe inner lining layer, and then covering the composite pipe outer protective layer. The composite pipe is resistant to high pressure, high and low temperature, and has strong wear resistance and oil resistance.

[0004] However, since the pipeline will be squeezed during use, the existing composite pipe itself has a low anti-extrusion ability and is prone to impact damage, thereby affecting the internal electrode system. Utility Model Content

[0013] Preferably, a support tube is provided between the first temperature-resistant ring and the reinforcing assembly, the support tube is made of metal material, and openings are evenly formed on the surface.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Through the relative arrangement of multiple first connecting strips and second connecting strips, a protective skeleton is formed inside the composite pipe, and the pressure resistance inside the composite pipe is strengthened by multiple reinforcing blocks.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A heat-resistant fiber-reinforced composite pipe comprises: an inner pipe 1, an outer pipe 2 is sleeved on the outer side of the inner pipe 1, a reinforcing component 3 is arranged between the outer pipe 2 and the inner pipe 1, and the reinforcing component 3 is used to enhance the resistance of the composite pipe to heat;

[0023] The reinforcement component 3 includes a first connecting strip 31, a second connecting strip 32, a reinforcement block 33 and a spiral strip 34. Multiple first connecting strips 31 are annularly arranged on the side of the outer tube 2 close to the inner tube 1, multiple second connecting strips 32 are annularly fixedly connected to the side of the inner tube 1 close to the outer tube 2, multiple reinforcement blocks 33 are fixedly connected to the side where the first connecting strip 31 and the second connecting strip 32 are close to each other, the upper and lower side reinforcement blocks 33 are staggered, and multiple spiral strips 34 are fixedly sleeved on the outside of multiple first connecting strips 31.

[0024] In the utility model, a protective skeleton is formed inside the composite pipe by the relative arrangement of multiple first connecting strips 31 and second connecting strips 32, and the compressive resistance inside the composite pipe is strengthened by multiple reinforcing blocks 33. The staggered reinforcing blocks 33 can ensure sufficient resistance, and at the same time, the force is dispersed through the spiral structure, thereby strengthening the resistance of the composite pipe. The annular reinforcing component 3 reduces the weight of the composite pipe while ensuring the overall resistance. The utility model is provided with a reinforcing structure with strong resistance to ensure the protection of the internal electrode by the composite pipe.

[0025] In the preferred technical solution of this embodiment, the reinforcing block 33 is a triangular block made of elastic material, and a triangular opening is opened inside the block for buffering. The triangle has stability, and the reinforcing block 33 can ensure the external impact resistance;

[0026] A plurality of spiral strips 34 are arranged equidistantly to form a protective sleeve. The cross section of the spiral strip 34 is triangular, and the tip faces the outer tube 2. The triangular spiral strip 34 can withstand more pressure. At the same time, the spiral strip 34 can guide the force to ensure the internal support and protection effect.

[0027] A temperature-resistant component 4 is provided between the outer tube 2 and the inner tube 1, and the temperature-resistant component 4 is used to ensure the temperature resistance of the composite tube;

The first temperature-resistant ring 41 is arranged between the outer tube 2 and the reinforcement component 3, and the second temperature-resistant ring 42 is arranged between the inner tube 1 and the reinforcement component 3. The inner and outer layers of the temperature-resistant rings can provide sufficient temperature-resistant protection for the entire composite tube. Even if the first temperature-resistant ring 41 on the outside is broken, the second temperature-resistant ring 42 located inside can also provide temperature-resistant protection under the protection of the reinforcement component 3.

[0029] A support tube 5 is provided between the first temperature-resistant ring 41 and the reinforcing component 3 . The support tube 5 is made of metal material and has openings evenly formed on its surface. The support rod 5 is used to rigidly support the entire composite tube to ensure the internal support strength.
